Add Process support for UEFI UEFI does not have an actual process. However, it does provide methods to launch and execute another UEFI image. Having process support is important since it is possible to run rust test suit using `Command::output` and is the first step towards being able to run it for UEFI. Here is an overview of how the support is implemented. - We create a copy of the SystemTable. This is required since at least OVMF seems to crash if the original system table is modified. - Stdout and Stderr pipe works by registering a new `simple_text_output` Protocol and pointing the child system table to use those. - `Stdio::Inherit` just points the console to the current running image console which seems to work with even 3 levels of process. - `spawn` is left unimplemented since it does not make sense for UEFI architecture. Additionally, since https://github.com/rust-lang/rust/pull/105458 was merged, the `spawn` and `output` implementations are completely independent. |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrate with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
